The API samples of scheduler-hints contains "hypervisor" and "near"
attributes, but the attributes do not exist in the scheduler-hints
parameter of "create a server" API. This patch changes them to the
existing "same_host" attribute.
This patch also changes the attributes of some unit tests of the v3
scheduler-hints by the same attribute.
This nonexistent attributes are found during bp/nova-api-validation-fw
works. The implementation needs this change because it will deny the
unexpected attributes, which are not defined with API schema, in API
parameters.
